Learning objectives (2)
A policy chart often contains one clean arrow from an instrument to an outcome. An institutional history often contains one clean line from a crisis to a law. Both are useful compression, and both become dangerous when the intermediate evidence disappears.
Open the monetary-policy chain
Start with current authority, the decision body, information date, instrument, decision, and implementation. Then trace financial conditions: short rates, broader yields, credit terms, asset prices, exchange rates, and expectations. Private contracts and balance sheets translate those conditions into borrowing, saving, investment, spending, production, and hiring. Output, employment, and prices respond with variable timing and magnitude.
The mechanism is not a causal estimate. Separate anticipated policy from the surprise component, reconstruct the information set available at the time, add contemporaneous shocks and revisions, and state the counterfactual design.
Open the fiscal-policy chain
Identify enacted or delegated authority, effective dates, eligibility, sunset, and implementation. Separate government purchases from transfers, automatic stabilizers from discretionary actions, and obligations from cash outlays. Trace incidence, timing, capacity, behavior, leakage, financing, and monetary conditions before narrating aggregate demand or prices.
A budget estimate inherits its baseline and model. An observed deficit is not the automatic-stabilizer effect by inspection, and an appropriation is not a vendor's earned revenue.
Match the document to the claim
Statutes create authority. Agencies implement or explain roles. BEA and BLS publish statistical measures under defined methods. The private NBER committee maintains a retrospective chronology. Complaints, trial findings, appellate opinions, settlements, and remedies occupy different legal postures. Historical accounts organize supported sequence but do not identify one cause by narration.
Use the Standard Oil and Microsoft cases to keep economic and legal tracks parallel. Use the Great Depression and Great Recession cases to keep output, prices, labor, finance, international conditions, policy actions, and later institutions on dated lanes.
Stop before the entity entry or recommendation
Macro conditions can alter contracts, expected cash flows, discount rates, credit risk, liquidity, taxes, grants, and demand. Entity conclusions still require a reporting unit, rights and obligations, event date, measurement date, scenario evidence, recognition criteria, disclosure, and current authority.
Recommendations add objectives, alternatives, constraints, distribution, side effects, uncertainty, and decision ownership. A supported mechanism is valuable even when these later ledgers remain open.
Exit check
Rewrite: “The Fed caused disinflation, fiscal spending ended the recession, and the Great Recession proves the same mix will work next time.” Identify current authority, dated actions, channels, lags, information sets, baselines, other shocks, counterfactual gaps, distribution, entity evidence, and the person or institution authorized to decide.
